Abstract: Procédé et système d'entraînement au sprint adaptés à divers animaux tels que les chevaux, les chiens et l'homme, ce système visant à appliquer une force de retenue pendant l'entraînement pour conditionner un animal à courir plus vite. Une voie (19) d'exercise est définie par un monorail (20) unique situé en hauteur. Le monorail (20) porte coulissant un ensemble de retenue qui produit une force contraire et généralement alignée dans le sens opposé au sens de déplacement de l'animal, le long d'une voie (19) d'exercice.

Abstract: An implement frame construction includes a fore-and-aft extending apertured tube with transversely extending tool mounting tubes with cross section matching the shape of the apertures. The tubes are inserted through the apertures to provide a mechanical connection not solely reliant on joint weld strength. The resulting joints are fillet welded on both sides of the fore-and-aft tube and provide more bending and torsional resistance than a butt-welded joint without need for gussets. The smaller tube runs continuously through the joint to reduce the number of components and welds necessary for a given frame configuration. The components themselves position the frame tubes relative to each other to simplify weld fixturing and increase resistance to parallelograming. Hinge areas are provided with welded tube-within-tube construction to prevent wall collapse and retain mounting bolt torque. A main frame section is constructed with continuous fore-and-aft extending hitch tubes which transfer loading directly from the transverse tubes to the towing vehicle and include aft ends for supporting trailing hitch structure. Wing frame sections are built with a similar tube construction, and one frame configuration may be used for right or left wings.

Abstract: The invention relates to a device used to connect a longitudinal support (1) to a pedicle screw (2) by means of an accommodating head (3) having a channel (5) to accommodate the longitudinal support, wherein it is possible to freely choose from or mix laterally open, top open or closed accommodating heads. A top open accommodating head (3) facilitates, for example, insertion of the longitudinal support (1), whereas a lateral opening enables lateral corrections. The pedicle screw (2) and the accommodating head (3) are connected via a conical collet chuck (7) in the accommodating head (3) and by a spherical head on the pedicle screw. It is thus possible to subsequently engage the accommodating head (3) and screw in the pedicle screw (2) even without the accommodating head (3), thereby allowing better visibility when assembling the pedicle screw. According to the embodiment, a clamping member (10) for the longitudinal support (1) is built into the clamping screw (36) of the spherical head (9) or integrated into the intermediate element (12) and the longitudinal support (1) and the spherical head (9)) can be fastened separately.

Title: Splicing of video data in progressively refreshed video streams
Inventor: LUTHRA AJAY
IPC: H04N7/24
Filed: 1999-10-18
Granted: 2006-10-17
Abstract: A method is provided for replacing compressed video from a first source with video from a second source at a predefined insertion point in a video data stream. If the video from the second source is progressively refreshed video, it is decompressed sufficiently prior to the insertion point to enable the recovery and recompression of a first video frame (in encoding order) from the second source to be inserted at the insertion point. The recovered first video frame is then recompressed as an intra-coded (I) frame. The insertion of the video from the second source is then commenced at the insertion point using the I frame. The insertion point can, for example, indicate the commencement of a commercial break in the video stream, in which case the second source provides a commercial for insertion into the commercial break. Where the commercial is stored in memory, it can be stored with the first frame thereof (in encoding order) as an I frame.

Abstract: This invention provides an apparatus and process for producing heavy crude oil from a subterranean formation penetrated by a well bore. In accordance with the process, an aqueous alkaline chemical solution is introduced into or formed in the well bore penetrating the formation. The aqueous alkaline chemical solution mixes and reacts with produced heavy crude oil in the well bore and ultrasonic waves are emitted into the mixture whereby an emulsion is formed. The viscosity of the formed emulsion is less than that of the crude oil or the crude oil and water mixture flowing into the well bore which allows the oil to be more efficiently pumped to the surface and transported for further processing.

Abstract: The invention relates to a method of operating a communication network, the network comprising a plurality of stations which are able to transmit data to and receive data from one another. The method comprises monitoring, at each station, the transmission path quality between that station and each other station with which that station can communicate. Data corresponding to the monitored path quality is recorded at each station, thereby permitting a transmission power value based on the relevant path quality data to be selected when transmitting data to another station. Thus, the probability of transmitting data to any selected station at an optimum power level is increased. Each station transmits path quality data in its own transmissions as well as local noise/interference data, so that other stations can obtain path quality data for a particular station even if they are out of range of that particular station. The invention extends to communication apparatus which can be used to implement the method.

Abstract: A coded bit stream 30 generated on a coding side consists of a VO header 30a, a VOL header 30b, a GOV header 30c, a VOP header 30d and VOP data 30e, and the VOL header 30b multiplexes an object intra-coded indicator signal 7' indicating whether all the VOP data 30e contained in a VOL or GOV are intra coded or not. This enables a decoding side to recognize whether all the VOP data 30e contained in the VOL or GOV in the coded bit stream 30 are intra coded or not by only analyzing the object intra-coded indicator signal 7'. This can facilitate such processings as frame skip control or random access of the VOPs.

Title: Device responsive to myoelectrical activity for triggering ventilatory support
Inventor: SINDERBY CHRISTER
IPC: A61B5/0488
Filed: 1999-02-26
Granted: 2009-08-11
Abstract: A device for triggering ventilatory support to assist the patient's respiration. Myoelectrical activity of a patient's respiratory-related muscle is sensed to detect respiratory effort and to produce a myoelectrical signal representative of the sensed muscle myoelectrical activity. Respiratory flow and pressure can also be measured to produce respective respiratory pressure and respiratory flow signals. A logic trigger circuit triggers ventilatory support in relation to the myoelectrical signal, respiratory flow signal and/or respiratory pressure signal to assist respiration of the patient. The amplitude of the myolectrical signal is compared to a given threshold, and ventilatory support is triggered when the amplitude of the myoelectrical signal is higher than this threshold. Increment of myoelectrical signal amplitude can also be detected to trigger ventilatory support, while decrement of the myoelectrical signal amplitude can be detected to request non-triggering of the ventilatory support.

Abstract: An optical fiber amplifier of the erbium type is intended to amplify light signals within a wavelength band, e.g. in the range of 1540 - 1555 nm. The active optical fiber (21, 23, 35) receives light signals to be amplified and pump light of a first pump wavelength from a pump source (9). A gain flattening filter (39) is connected in the active optical fiber length. A noise filter (37) is also connected in the active optical fiber, not more closer to the output end of the active fiber than the gain flattening filter (39). The noise filter (37) blocks light waves having wavelengths around the ASE gain peak and the gain filter (39) attenuates wavelengths within the useful signal band in order to produce a flat gain curve. The introduction of the noise filter (37) increases the total amplification of the amplifier.
